2014-03-05drm/nv50/disp: use correct register to determine DP display bppIlia Mirkin
commit a7f1c1e65b68e1e1ab70898528d5977ed68a0a7d upstream. Commit 0a0afd282f ("drm/nv50-/disp: move DP link training to core and train from supervisor") added code that uses the wrong register for computing the display bpp, used for bandwidth calculation. Adjust to use the same register as used by exec_clkcmp and nv50_disp_intr_unk20_2_dp.

2014-02-06drm/nouveau/bios: fix offset calculation for BMPv1 biosesIlia Mirkin
commit 5d2f4767c4eacab351b8450b0de4d3261fe1a957 upstream. The only BIOS on record that needs the 14 offset has a bios major version 2 but BMP version 1.01. Another bunch of BIOSes that need the 18 offset have BMP version 2.01 or 5.01 or higher. So instead of looking at the bios major version, look at the BMP version. BIOSes with BMP version 0 do not contain a detectable script, so always return 0 for them.

2014-01-09ACPIPHP / radeon / nouveau: Fix VGA switcheroo problem related to hotplugRafael J. Wysocki
commit f244d8b623dae7a7bc695b0336f67729b95a9736 upstream. The changes in the ACPI-based PCI hotplug (ACPIPHP) subsystem made during the 3.12 development cycle uncovered a problem with VGA switcheroo that on some systems, when the device-specific method (ATPX in the radeon case, _DSM in the nouveau case) is used to turn off the discrete graphics, the BIOS generates ACPI hotplug events for that device and those events cause ACPIPHP to attempt to remove the device from the system (they are events for a device that was present previously and is not present any more, so that's what should be done according to the spec). Then, the system stops functioning correctly. Since the hotplug events in question were simply silently ignored previously, the least intrusive way to address that problem is to make ACPIPHP ignore them again. For this purpose, introduce a new ACPI device flag, no_hotplug, and modify ACPIPHP to ignore hotplug events for PCI devices whose ACPI companions have that flag set. Next, make the radeon and nouveau switcheroo detection code set the no_hotplug flag for the discrete graphics' ACPI companion.

2014-01-09nouveau_acpi: convert acpi_get_handle() to acpi_has_method()Zhang Rui
commit 187b5b5d520c2318a1f88fb8d8913a9d7fbf7d92 upstream. acpi_has_method() is a new ACPI API introduced to check the existence of an ACPI control method. It can be used to replace acpi_get_handle() in the case that 1. the calling function doesn't need the ACPI handle of the control method. and 2. the calling function doesn't care the reason why the method is unavailable. Convert acpi_get_handle() to acpi_has_method() in drivers/gpu/drm/nouveau/nouveau_acpi.c in this patch.

2013-09-04drm/nouveau/bios/therm: handle vbioses with duplicate entries (mostly nva5)Martin Peres
Some vbioses have extra useless entries after "the end" of the table. This is problematic since all of the vbios I found with this issue redefine the pwm freq divider to insane levels (52750 Hz instead of 2500), thus breaking fan management. The first solution to solve this mess would be to change the length of the table. The solution I choose was simply to avoid setting the pwm freq twice as the other redefinitions are harmless with our current parser.

2013-09-04drm/nouveau/therm: survive to suspend/resume cyclesMartin Peres
Therm uses 3 ptimer alarms. Two to drive the fan and one for polling the temperature. When suspending/resuming, alarms will never be fired.

2013-08-27drm: verify vma access in TTM+GEM driversDavid Herrmann
GEM does already a good job in tracking access to gem buffers via handles and drm_vma access management. However, TTM drivers currently do not verify this during mmap(). TTM provides the verify_access() callback to test this. So fix all drivers to actually call into gem+vma to verify access instead of always returning 0. All drivers assume that user-space can only get access to TTM buffers via GEM handles. So whenever the verify_access() callback is called from ttm_bo_mmap(), the buffer must have a valid embedded gem object. This is true for all TTM+GEM drivers. But that's why this patch doesn't touch pure TTM drivers (ie, vmwgfx). v2: Switch to drm_vma_node_verify_access() to correctly return -EACCES if access was denied.
